Short answer: the JBL Boombox 3. It ranks #27 of 98 boombox speakers by sound quality, rated 3.8/5, at $349.95. The JBL Partybox On the Go ranks #64, rated 3.0/5, at $249.95, $100 cheaper, a saving that is not big enough to make up the sound-quality gap.
The JBL Boombox 3 is the better-sounding, deeper-bass option. 24 hour battery life (6.5 hour charge time). Its bass reaches about 43Hz before falling 10dB, against 49Hz for the JBL Partybox On the Go. It is rated for 24 hours of battery against 6 for the JBL Partybox On the Go. It is rated IP67 against IPX4 for the JBL Partybox On the Go. The catch: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
What the JBL Partybox On the Go does well: JBL Partybox On the Go uses 5.1” woofer + tweeters. Watch for: Bass is limited by its 49Hz specification.
Buy the JBL Boombox 3. It is rated higher for sound quality, and the $100 saving on the JBL Partybox On the Go is not enough to make up the difference.
